Near diffraction-limited laser output from a very large size rectangular core crystalline waveguide

Near diffraction-limited laser output from a very large size rectangular core crystalline waveguide laser was achieved experimentally. A crystalline waveguide, with a rectangular core size of 320     μ m × 400     μ m by 1.0   at.% Yb:YAG (core) and ...
